Grapevine plant named ‘Sheegene 27’

ABSTRACT

A new and distinct grapevine plant named ‘Sheegene 27’ is described herein. The claimed variety was developed as a table grape and for raisin production, having uniform medium-sized, green, globose, seedless fruit weighing approximately 3 g each and having a crisp texture and neutral flavor. Harvest is in late-July to mid-August.

Latin name of the genus and species of the plant claimed: Vitisvinifera.

Variety denomination: ‘Sheegene 27’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grapevinenamed ‘Sheegene 27’. ‘Sheegene 27’ produces medium-sized, green-yellow,seedless grapes on bunches for use as a table grape and in raisinproduction. The variety originated from a cross of ‘Very Early Flame’(also known as ‘VEF’) as the pollen parent and ‘Red Globe’ (U.S. PlantPat. No. 4,787) as the seed parent. ‘Sheegene 27’ was first asexuallypropagated in the San Joaquin Valley of California. All characteristicsand distinctions remain true to form and are established and transmittedthrough succeeding propagations.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct grapevine plantcalled ‘Sheegene 27’. ‘Sheegene 27’ produces medium-sized berriesaveraging 3 g per berry. The berries are harvested in late-July tomid-August. Comparison can be made to ‘Thompson Seedless’ (unpatented),which is also a green, seedless grape grown for both table grape andraisin production. ‘Sheegene 27’ matures 10 days earlier than ThompsonsSeedless, and about the same time as Selma Pete, a grape cultivar grownfor raisin cultivation. Berries of ‘Sheegene 27’ are globose, while bothThompson Seedless and Selma Pete are ellipsoid pointed. ThompsonSeedless and Selma Pete berries weigh approximately 2 grams, while‘Sheegene 27’ berries are larger, weighing around 3 grams.
